Maui richtexteditor text changed event

[David]

is there a way to get a textchanged event on the richtexteditor?

Hello David,

Currently there is not a TextChanged event. We do have a Feature Request open for this (RichTextEditor: Provide a notification for content changes), I have gone ahead and added an upvote on your behalf.

In the meantime, the only way to determine changes is to compare before and after the suspected change:

// Maybe store this a private field
var initialHtmlString = await this.richTextEditor.GetHtmlAsync();

// SOME TIME/EVENT OCCURS (e.g. keyup event)
public bool CheckEditorContentChanged()
{
    var htmlStringToCompare = await this.richTextEditor.GetHtmlAsync();

    if(initialHtmlString.Equals(htmlStringToCompare))
    {
        // nothing changed
        return false;
    }
    else
    {
        // text content, formatting, style, etc has changed
        return true;
    }
}

Hello Lance,

i've tried to work around this using the Focused and Unfocused event on RichTextEditor.
But unfortunately both aren't fired. Any suggenstions?

thx
Nico

Hi Nico,

The focused and unfocused events do not fire. This is due to the interval WebView we use in the RichTextEditor control.

Cast your vote for the following feature request for focusing the control programmatically: https://feedback.telerik.com/maui/1675327-richtexteditor-provide-an-option-to-focus-the-control-programmatically

Hi Didi,

after a deeper look into how the control works inside i've found a workaround:

It should only be a small effort for Telerik to implement the corresponding feature request and thus give others the TextChanged event.
Or alternatively to make the focused and unfocused event of the internal RadTextView available in the RadRichEditor

But at least there is now a workaround that others who are looking for it can work with

Hi Nico,

Thank you for the update. May I ask you to add the workaround as a comment to the public item here: https://feedback.telerik.com/maui/1675327-richtexteditor-provide-an-option-to-focus-the-control-programmatically

Thank you in advance.
